Since the oil price spike of 2008, there has been greater interest in public transit and the walkability of communities. About 3/4 of liquid fuels in the United States goes to transporting people and goods. Carpooling or taking the bus, instead of single person car trips decreases CO2 emissions and reduces the cost of commuting. The option to walk, bike, bus or carpool gives people more choice and makes for a healthier community and a better planet.
